IMPROVEMENT IN CAR-BRAKES.

Specification forming part of Letters Patent No. 128,277, dated J une 25, 1872; antedated June 15, 1872.

To all whom it may concern:

Be it known that I, WILLIAM BALL, of Oregon, in the county of Holt and State of Missouri, have invented a new and valuable Improvement in Oar-Brakes and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of an under-side plan view of my invention. Fig. 2 is a vertical longitudinal-section of the same.

This invention has relation to railroad-car brakes; and the novelty consists in theconstruction and arrangement of devices, hereinafter described, for the purpose of operating all the brakes on a train-from one platform in an efi'ectual manner, and with all the requisitespeed, as hereinafter described.

Referring to the accompanying drawing illustrating this invention, A represents the body of a railroad car or engine-tender rest-- ing on the trucks B B having the ordinary wheels 0. D designates transverse brakebars provided with metallic brake-shoes cl, and hinged to the truck-frames B B by means of links 01. E represents a longitudinal bar running underneath each car and projecting beyond its ends, as shown at c in the drawing. The bar E which runs along under the enginetender projects beyond the rear end only. The forward end extends to about the middle of the forward truck, where it is provided with a narrowed metallic shank, F, which enters an open tube or box, F, rigidly secured to said truck, and containing a coiled spring, g. The shank F is provided with a head, against which one end of the spring rests, the other end touching the cross-bar or bolster g The bar E, which is designed to move longitudinally, is braced and guided by means of two slotted plates, 6 6, attached to it by means of a screw, 6 The truck-bolt G passes through the slots in the plates 0 e, and also through a slot, 6 in the end of the bar E. H designates a horizontal transverse shaft journaled to a lug, h, projecting from the end of the tube F and to astandard, h, depending from one side of the tender or car-platform. To

from the end of the shank F the spring g forces j the bar E forward to its first position. A crank-arm, J, is secured to or formed on the shaft H, and connected, by means of a rod, K, to the lower end of a lever, K which is pivoted to a bracket, K, projecting from the forward end of the forward truck. The upper end of this lever extends so as vto be within reach of the engineer or conductor. By moving this lever in the proper manner all the brakes in a train of cars may be operated. The bars E, which are attached to all the cars, pass through openings formed in the bolsters or transverse beams of the wheel-trucks B. At either side of these openings, and within suitable recesses,'lever-plates L are arranged. They are constructed with inwardly-proj ectin g lugs M, which are pivoted to the bar E. These plates are also connected, by means of chains N, with the brake-bars D, and hence, according to the direction which the bar E is moved, tighten or loosen the brakes. The chains N are attached to the brake-bars D by means of bolts a passing through them, and provided with nuts on both sides, so that any slack in the chain may be easily taken up. 0 indicates a transverse shaft journaled to one of the trucks of each car and of the tender. Secured to said shaft is an eccentric drum or pulley, P, around which winds a chain, P, which is connected to the bar E. The shaft 0 is provided with an arm, P, by the working of which the bar E is moved to operate the brakes. Each of the bars E which are attached to the cars in a train are furnished withheads E.

When the bar of the tender or any of the cars is moved so as to bring the brakes in effeet the bars of the succeding cars closing up come in contact with the projecting ends of the bar of the tender or first car, and, being In testimony that I claim the above I'have moved thereby, operate the brakes of all the hereunto subscribed my name in the presence cars. l of two witnesses.

What I claim as my invention, and desire WILLIAM BALL. to secure by Letters Patent, is

The car-brake herein described, consisting Witnesses: of the longitudinal bar E, plates L, chains N, CLARKE IRVINE,

' brake-bars D, shaft H, cam I, and spring g, T. O. DUNGAN.

substantially as shown and. described.
